-' OI IANGE-MAKING MACHINE.

To all whom it may concern:

Be it known that I, JOHN THOMAS,GAR.-. TON, of the city of Toronto, in the county of My invention relates tochange making machines: in which mixed coins are sorted out, and from which any desired coin or coins may be discharged by depressing certain keys, and my object is to devise apparatus of this xkllltl which will more effectively sepathan those now known, and which may be caused to deliver any desired coin or coins with absolute certainty.

The basis of my machine is a'series' of'sepa-- rating screens each. provided with a number of suitable lioles so 'that it will sto and tail off one size of. coin andp'ass al coins of I have found by careful experiment that such screens will not properly separate mixed coins unless they are agi is constructed so enliployed to eject coins from the a paratus W1 agitate the screens and shake t own the coins thereon.

In the d dicate corresponding parts in the differentfigures.

A is a suitable casing provided at the topwith a hopper B, and also provided with one or more drawers C for bills.

The sorting part of the device com rises a series of sorting screens D, suitab y con nected and supported so that they may be? vibrated, suitable hangers such as abeing provided for this purpose. A hanger b, is also employed to aid inthe agitation of the screens. Each screen. is provided with holes of a suitable size to, enable it to retain all coins of the size it is expected to tail 0H and to pass all smaller coins, The-lowest screen will of expected to tail off all COlIlS assed to it, the' number of screensemploye depending of course on the Specification of Letters Patent.

number of different sizes of coins employed in the country in'which the device is used. I have illustrated the device as used with Canadian silver money, namely fifty cent pieces, twenty-five cent pieces, pieces and five cent pieces.

Each screen discharges int-o one of the spouts E. These spouts lead to the coin tubes F of suitable size to receive the different coins. Each coin tube is preferably )I'O- vided with a slot 0 in the front thereof which enables the operator to see when the tubes become empty, an opening (I being provided in the casing through which thetubes may be A coin expelling slide G, of the same thickness as the coins contained in.the tube, is adapted to be projected across the bottom of the tube, and is carried on the guide way e: By projecting one of these slides reab wardly a coin may be projected through the 'uide' way (2 and into the com .chute'H, which loads, as shown, to the outside of the machine and discharges the coins received by \it on to the counter.

Each slide G is normally maintained in its,

means ofa coil spring forward position by For the purpose of provide a withilf the casing A, .and projecting out therefrom as shown. Each key atits inner operating the-slides G I .end has a sliding engagement with a bell crank lever J, suitably fulcrumed within thecasing. The other arm of each bell crank lever has a sliding engagement with a lug g to which the springfisattached. It is evident that by depressing a key the correspondingslide will be shot rearwardly, and onthe release of the key the slide-will be returned to its normal position by the spring j: J

I have found from experience that coins cannot be properly sorted out by any systen'i of stationary screens. If the screens be set on too small an inclination the coins will not slide'down them. If the screens are at a sufficient inclination for the coins to slide freely many coins will be tailed'olf that should pass through. I have therefore devised means whereby the screens may be agitated each time-a key is depressed to makechange. For this purpose I provide a bent lever K 'fulcrumed on the casing, and having one screens D, and the other provided with a bar series of keys I, suitably fulcrumed arm It in a position to engage the l formed on the bell crank levers J.

A coil spring I connected to the lever and to a suitable stationary part tends to main-' tain the leyer'K in its normal position. Thedepression of a key, however, causes oneof the arms i to strike the bar j, thus rocking the bent lever K and causing the latter to jar the screens. This agitation is suflicient to shake down the coins, and it will be observed that it does not require any thought on thepart of the operator but takes place automatically every time he makes change. It is desirable, however, to devise means whereby when a coin is first placed in the machine it may be sorted out without the necessity of depressing the change making key. I

therefore journal in the casing a shaft L, provided within the casing with a cam 1 adapted to strike and agitate the screens, and outside the casing provided with a crank handle M, by means of which. it may be rotated when desired. Y 7

It will be seen therefore that I have devised effective means for properly sorting coin of all kinds, and for delivering the same in any desired quantity and of any desired 3 denomination by 'the simple operation of depressing one or more keys.

W'hat I:claim as my invention is 1. In apparatus of the class described the combination of suitably supported sorting screens; a plurality of coin delivering devices to which the said screens deliver; keys adapted to operate-said devices; and means whereby the 'operation of a key will agitate the screens.

2. In apparatus of the class described the combination of suitably supported sorting screens ;'a plurality of coin delivering devices to Which said screens deliver; keys adapted to operate sald devices; means whereby the operation of a key will agitate the screens; and a device independent of the key for agitating the screens.

3. In apparatus of the class described the combination of sorting screens movably supported; a lever fulcrumed intermediate its ends and adapted at one endto engage the screens a pivoted key adapted to engage and rock the other end of said lever; and a spring tending to retain the lever in its norrnal position.
